So I wanted to replace my 8.2 10 bolt 4.11 with 3.08 and bought a ring and pinion and a master bearing replacement set. The new bearings fit perfectly on the carrier and the large bearing for the pinion fit well but I came to realize that the small bearing for the pinion is way too small and the spline on the 3.08 pinion is huge. I didn't notice that at first cause I was too concerned with the height matching and totally overlooked the thickness of the shaft and spline. I'll admit i'm a novice when it comes to rebuilding rear diffs but I thought since I went down in ratio that there wouldn't be no change for the pinion size except for the amount of teeth on the pinion gear and that was it. Boy was I wrong. This really threw me for a loop and made me realize I really don't have things figured out like I thought. Base on the pics can anyone tell me if the pinion on the right is even the correct one for my application? I know I have an 8.2 10 bolt set up and when I bought the 3.08 set up the description on the listing was for a 8.2 10 bolt. So why is the pinion so different? If I go this route I will need to replace the yoke and if I replace the yoke will I need to replace the driveshaft?
